You can find contact details on the contact card in the Details tab. Imported details can be changed by means of Workflow after a specific event takes place. If the activity of the contact changes, each detail can be changed automatically if you set a particular action in Workflow.
Go to AUTOMATION PROCESSES => WORKFLOW
From the list of the elements in Workflow choose Action => Add/change contact detail
Then, go to the settings of the rule.
In this action you can adjust the settings of the following elements:
[Detail name]: enter a new name for a detail or existing one if you only want to change the detail value.
[Detail value]: enter a new value of a detail.
Once you’re done, click Save changes to continue.
